Patent CA-2249349-A1 (CA)
Inventor: CORBEAU PIERRE
IPC: C12N5/10
Filed: 1997-03-26
Abstract: Cette invention concerne la production d'une lignée cellulaire d'encapsulation stable de VIH-1 dénommée ? 422, laquelle est obtenue en effectuant la transduction de cellules dans la séquence d'encapsulation principale desquelles un clone moléculaire de VIH-1-MN a été effacé. Les cellules ? 422 permettent d'obtenir des syncytiums à cellules positives CD4, expriment correctement les protéines structurelles de VIH-1, et permettent de produire de grandes quantités de particules mûres possédant une activité RT normale, ces particules n'étant pas infectieuses. Une fois la transfection effectuée de manière stable avec un vecteur rétroviral de type VIH-1, la lignée cellulaire ? 422 permet de produire des virions hybrides capables d'effectuer la transduction des cellules positives CD4 avec une grande efficacité (par exemple, 10?5¿ cellules/ml). Cette lignée cellulaire stable et non infectieuse d'encapsulation de VIH-1, est capable de générer des vecteurs de VIH possédant un titre élevé, tandis que sa disponibilité permet d'utiliser des systèmes d'administration d'acides nucléiques de type VIH-1 lors d'une thérapie génique, par exemple. Un vecteur de type VIH-2 peut être encapsulé par les lignées cellulaire d'encapsulation, ce qui permet de démontrer que les vecteurs de transformation cellulaire de VIH-2 sont encapsulés par la lignée cellulaire d'encapsulation. Il a été observé que les vecteurs de type VIH encapsulés par ces lignées cellulaires d'une grande efficacité, possèdent d'eux mêmes une activité anti-VIH.

Title: Odor-proof sealable container for bodily remains
Inventor: MCWILLIAMS EDWARD L
IPC: A61G17/06
Filed: 1997-03-20
Abstract: Containers are described for retention of human or animal remains for extended periods. The bags are constructed of laminated materials and sealed, which prevents the escape of noxious or odorous decomposition gases or harmful decomposition fluids into the ambient surroundings. The invention also provides for infusion or extraction of gases to retard the decomposition of the contained remains. The container is constructed of flexible multilayer laminated walls forming an interior chamber for accommodation of remains, and after the remains are emplaced the container's opening is sealed. The multilayer laminate includes at least two layers of polymeric sheet material with a metal foil layer between them, although use of more complex polymer/metal laminates is also described. The polymeric layer materials include polyolefin, nylon or polyvinyl sheet materials and the metal foils are normally aluminum foil. The containers may be furnished flat to the end user and joined in series coiled into large rolls from which the user merely cuts off desired lengths as needed. The roll structure and sealing method may also be used with other types of containment bags.

Patent CA-2256132-A1 (CA)
Inventor: STRAUSS BRIAN M
IPC: A61B17/22
Filed: 1998-12-16
Abstract: A miniaturized obstruction treatment device, e.g., a resilient brush, particularly adapted for medical use formed at the distal end of an elongated brush drive shaft having a hollow lumen formed therein for introduction over a guidewire. The brush drive shaft is enclosed in the lumen of a brush delivery catheter, and the brush is adapted to be garaged in a distal end section of the brush delivery catheter lumen. A Y-connector and a brush sub-assembly connector are attached to the proximal end of the brush delivery catheter and form a brush sub-assembly with the brush drive shaft and brush. The Y-connector allows infusion of thrombolytic agents into the brush delivery catheter lumen for emission at the distal end opening thereof adjacent the brush. In use, the brush sub-assembly connector connects the brush sub-assembly with a drive motor unit connector of a drive motor unit. The drive motor unit receives the proximal end of the drive shaft and rotates it to rotate the brush bristles. The brush and brush drive shaft distal section are automatically extended out of the catheter lumen distal end opening when the sub-assembly connector and the drive motor unit connector positively lock together. Simultaneously, a drive hub of the brush drive shaft locks into a drive chuck of a drive motor unit to enable rotation of the drive shaft, and the drive shaft proximal end is seated in a dynamic seal that inhibits infiltration of blood and thrombolytic agent into the drive motor housing.
